摘要
对激光二极管侧面抽运Nd:YAG板条双程功率放大器进行了研究,激光器基模输出平均功率大于200 W,建立了激光二极管侧面抽运Nd:YAG之字型板条激光主振荡-多程功率放大(MOPA)系统,它由两级Nd:YAG板条双通功率放大器构成,最后-级为单通放大器.在500Hz重复频率时,获得单脉冲能量为410mJ的1.06μm激光输出,光束质量M2小于6.5,KTP晶体在80℃温度下倍频,输出0.53 μm绿光单脉冲能量210mJ,光束质量M2小于6.5.
Abstract
Diode laser arrays side-pumped Nd:YAG slab double-pass laser power amplifier is studied in the paper. Experimental results and numerical simulations of laser performance are presented. ΜΟΡΑ system has been built up using gaussian beam as source. Over 210 mJ energy per pulse green laser output at 500 Hz repetition rate is achieved Beam quality M2 is less than 6.5.The fluctuation of the laser output energy is less than 2%. The result shows that the experimental data have been consistent with the numerical calculation results.
